Scientists observe flattest explosion ever seen in space

This illustration shows the ingredients of a long gamma-ray burst, the most common type. The core of a massive star (left) has collapsed, forming a black hole that sends a jet of particles moving through the collapsing star and out into space at nearly the speed of light. Radiation across the spectrum arises from hot ionized gas (plasma) in the vicinity of the newborn black hole, collisions among shells of fast-moving gas within the jet (internal shock waves), and from the leading edge of the jet as it sweeps up and interacts with its surroundings (external shock).

Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions

SKAO and partners advance support for protection of astronomy at UN

Astronomers just discovered a comet that could be brighter than most stars when we see it next year. Or will it?

The Hermanus Astronomy Centre covers the whole of the Overstrand from Rooi Els to Gansbaai, although anybody from elsewhere is welcome to join.

Monthly meetings are held on the third Tuesday of each month, usually at the Onrus Manor visitor's centre, and on Zoom for those who can't attend in person (login from 17:45). Other monthly meetings, also on Zoom (login from 17:45), include the Cosmology Group (on the first Tuesday) and the Study Group (last Tuesday).

The Astrophotography Group does not meet unless specifically requested. Interested persons please check the HAC Events calendar. Please send requests to petermh@hermanus.co.za .

For Sidewalk astronomy sessions, kindly refer to the HAC Events calendar and the website calendar.

The HAC events calendar (to the right) should be checked for details, for example "Moon-Gazing would be held after the New Moon." Other stargazing sessions are presented on request.
